If you need an address for an active duty Marine whether deployed or not, call the USMC Marine Locator. You must have identifying information about your Marine to get the address. Call Monday - Friday, 8:30 - 4:00 Pacific Standard Time. This number is NOT region-specific. They can help you for ANY active duty Marine including reserves that have been called to active duty.

For the latest unit addresses and information about sending mail to deployed Marines you should contact the Main Post Office at the installation where the Marine was assigned before deploying. Letters and packages sent to Marines at their stateside Marine Corps Postal addresses will be forwarded to deployed Marines with a minimum delay.
